摘要

近几十年来

塔里木河下游河道断流

地下水水位剧烈下降

天然植被衰退

为恢复和重建塔里木河下游严重受损的生态系统

从2001年到2006年

先后进行了8次生态应急输水。在实地考察和前人研究资料的基础上

对塔里木河下游生态输水的背景进行了介绍。分析了生态输水后地下水位恢复情况、地下水矿化度变化、植被对生态输水的响应以及生态输水对土地沙漠化情况的影响。结果认为

生态输水后塔里木河下游沿河道两岸一定范围内生态环境得到明显的改善

但仍存在一些问题

如目前生态输水主要建立在博斯腾湖和开都河高水位的基础上

如果遇枯水期则无法实现。若长期大量从博湖调水

必然导致博湖水环境的恶化。

Abstract

Over the pastdecades

zero-flow caused the reduction of groundwater level and the degradation of vegetation in the lower reaches of the tarim River. In order to rehabilitate and reconstructthe seriously dam aged ecosystem

eightemergentecological water conveyances were conducted from 2001 to 2006. The effects of ecological stream water conveyance on groundwater level and quality

vegetation

and land desertification were analyzed based on the field investigation and monitoring data. Results showed thatthe groundwater lev el and quality in the lower reaches of the tarim River have been significantly increased. Itcan be concluded from this study thatafter conveying water

ecological environmentwithin a certain range of the riversides in the lower reaches of tarim River is significantly improved. However

some problems still exist

for exam ple

the currentecological water conveyance is decided mainly by the high water level of Bosten Lake and Kaidou River. If a dry season is encountered

itis difficultto handle it. If a large quantity of water convey ance from Bo Lake

Bo Lake will inevitably lead to the deterioration of the environment.
